This issue still exists in the current latest drivers from October and November.

18.10.2

18.11.2

There is also a youtube video that demonstrates the issue at the 12:05 minute mark.

Hi Everyone.

Thank you folks on AMD forums for at least pointing me towards identifying my problem.

I have this exact same issue, here's the thing.

I've just upgraded from a RX580 to a RX5700XT and I'm just now experiencing this issue with Adrenalin 2019 Edition 19.9.2.

I've always had freesync enabled on my RX580, but I never saw this issue before I upgraded.

I really don't wanna have to disable Freesync.

My main monitor is an AOC 35-144 hz and my TV is just a 60hz, running HDMI from GFX to a receiver and HDMI throughput from the receiver to the TV.

As far as I can tell, Vega's were the only ones affected by this bug, but I can now confirm that Navi's has it too

I read earlier that reducing Hz from 144 to sub-120 might help with the problem, I'll try that when I get home and report back.

But yeah, the youtube vids posted earlier shows exactly what I'm seeing with 5700XT also.

OK - Changing my main monitor to 120/100/60 hz.  didn't do the trick.

I've messed around with all kinds of settings, but all to no avail.

You are not alone in this issue. I don not know that there is a work around for this issue. Make sure to report it to AMD: https://www.amd.com/en/support/contact-email-form

As far as I can tell, a Windows update from last year caused the issue. One day I decided to update both Windows and the drivers for my RX 480 (didn't have the issue before that), and the issue appeared. I rolled back the driver to the one I know didn't have the issue, and even tried older drivers - but it still persists. Been keeping Freesync disabled since then. Currently still having the issue on my Vega 64 when I enable FreeSync.

I'm almost tempted to install an older version of Win10 or even run Win 8.1 on my system.
